Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a function for quickly starting heating of a floor heating system.

Conventional floor heating is highly rated for its comfort, but its popularity is slow due to the slow start-up time of heating.

The characteristics are shown in FIG. 1, where the vertical axis shows the room temperature T and the horizontal axis shows the elapsed time t, which is the time t from when heating starts at time 0 until the set temperature T1 is reached.

The time was longer than that of the hot air type and the radiant type, which was a problem.

The present invention, as shown in the basic configuration of FIG. 2, uses a fan convector in combination to solve the above drawbacks.

1 is a heat source device (used as a hot water supply heat source) that heats and circulates water.

The circulating water passes through a fan convector 2 and branches from a branch pipe 3 to a bypass valve 4 and a floor heater 5.

After branching to the bypass valve and the floor heater, it rejoins and returns to the heat source device 1.

Using this configuration, the bypass valve 4 is turned ON when heating starts up.
Then, the heat is radiated as warm air by a fan convector, and when the room becomes warm, the bypass valve 4 is turned off and the heat is radiated by the floor heater 5 to obtain comfortable heating.

FIG. 3 shows an exemplary circuit of the present invention.

6 is a power source, and 7 is a power switch (used as an operation switch for the heat source device 1).

When the power switch 7 is closed, the power lamp 8 lights up and the combustion and hot water circulation control circuit 9 of the heat source device is driven to start heating, but when the fan convector switch 10 is turned on as shown in the figure (ON), the bypass is activated. valve coil 1
Since power is applied to 1, the heating water passes through the fan coil and the bypass valve.

At the same time, the fan 12 of the fan convector is driven to blow out warm air, and the lamp 13 is lit to indicate that the fan convector is in operation.

The warm air from the fan coil rapidly warms the room, and when the temperature reaches a suitable temperature, the switch 10 is turned OFF to stop the fan 12 and stop the hot air.

At that time, the bypass valve coil 11 is turned off, so
The heating water passes through a fan convector and begins dissipating heat from the floor heater.

Since the fan convector stops blowing air, there is little heat radiated by the fan convector, and most of the heat is radiated by the floor heater.

Next, the heating characteristics are shown in Figure 4, where the vertical and horizontal axes are
Same as figure.

When the fan convector switch 10 is turned OFF at time 0 time t2, where the time t1 required to reach the set temperature T1 due to hot air heating is much faster than in FIG. Return to normal.

FIG. 5 shows an embodiment of the present invention, and compared to the previous example,
The temperature setting in the heating water circulation circuit 9 is changed in conjunction with the reversal of the fan convector switch 100.

As a fan convector, the higher the temperature of the circulating water, the more efficiently it can heat the room, and the faster the temperature rises, so it is desirable to set it to around 85 degrees Celsius, for example. However, when heating the floor heater, some people feel hot when it is circulated at that temperature. There are many unfavorable things.

Therefore, it is usually necessary to maintain the temperature at about 60 to 70°C, and this method can satisfy both comfort and improvement in start-up speed.

Figure 6 shows its characteristics.

The room temperature characteristics are basically the same as in Fig. 4, but the temperature setting of the circulating water on the heat source side is as shown in Fig. 1.
It has been changed from i1TH1 to TH2.

In addition, up until now, we have explained an example in which the hot water circulation path is connected in series from the hot water supply heat source to the fan convector and the floor heater, but as shown in Figure 8, the fan convector and the floor heater are connected in parallel. The present invention is equally applicable even when connected to

20 is a three-way valve, and by switching this valve, the circulation route is switched between the fan convector 2 side and the floor heater 5 side.

21 is a confluence point.

The same explanation can be given by replacing the operation of the three-way valve 20 with the bypass valve 4 that has been previously explained.

As described above, the heater of the present invention has a hot water circulation control circuit that sets the setting value when the air blowing switch of the fan convector is on to a higher value than when it is off, so that the heating efficiency of the fan convector is improved. It is possible to satisfy both of the requirements of maintaining a high temperature and speeding up the start-up and maintaining the comfort of floor heater heating.
